IMPROVED BUTT-HINGES.

TO ALL WHOM I'l MAY CONCERN:

Be it known that I, MASON C. AMES, of the city and county of Hartford, and State of Connecticut, have invented certain new and useful Improvements in Butts; and to enable others skilled in the art to make and use thc same, Iwill proceed to describe its construction, referring to the drawings, the letters upon which indicate like parts in each of the gures.

The nature of this improvement will beA understood from the specification and drawings. I

This butt is :so constructed as te render it applicable and useful for almost all purposes for which butts are required. It is a loose or detachable-joint butt, aright and left-hand butt, a reversible, or what is sometimes called pew or slip-butt. It consists in forming the Whole size or diameter of the hinge or joint proper outside or tlush with one side of one half ot' the butt, while the other half has its portion of the hinge so made as to t the other, and at the same time allow it to close up against that side of the first to which the joint is made flush; or in other words, cnc halt` of the butt is made in the common way, while the other half, with its joint, is so made, that when it is secured by its axis-pin in its proper place it will close against what heretofore or in the common butt is called the outside, so that one part thereof may be drawn from the other, when the airis-piu is withdrawn, without separating the surface of one from the other. In the accompanying drawings- Figure 1 is a view of this butt, open` Figure f.- is a view of' the butt when closed.

Figure 3 is au end view thereof when open.

Figure i is a view ot' the same when closed.

1. and a are plates having screw-holes in the common way for securing the same to a door, jamb, Ste.; is the hinge formation; the part a is made much in the common way, while thepart a closes up against the outside, instead et', as in the ohl way, of closing:l together iu a line with the centre line ofthe axis-pin c. This butt may be used for any and all purposes for which it is desirable. It is a loose-joint butt, a right and left-hand butt, or itis what is sometimes called a slip-butt. It will also be observed that a door hung with this butt can be lifted with o'ne part of the but-t from the other, after the axis pin has been removed, when the door is open or when it is closed, beca-use the peculiar construction ot' the joint allows the part a to draw forward from the parta without being drawn forward from its surface or plate d. cis the axis-pin, provided with a plain or ornamental head upon one or both ends thereof, the object of which is to render it symmetrical in its appearance. These heads may be secured ou one or both ends of said axis-pin by a screw-thread n the common way. The advantage and utility of this improvement in butts is believed to be too obvious to need further example.

I believe I have thus shown the nature, construction, and advantage of this improvement, so as 'to enable others skilled to make and use the same therefrom.

What I claim, therefore, and desire to secure by Letters Patent, is-f- The arrangement of the hinge-joint b in its relative position with the plates a. a, substantially as and for M. c. AMES. [1.. 8.] Witnesses:
